3 Claims. (Cl. ZIN- 57) My invention relates to container closures such as are required for drums.

In the art, there has been. considerable development in the use of what is known in the 8 trade as a single tripper drum which is useful for shipping material such as lard compounds, edible fats and oils, and the like, and to the best of my knowledge and belief there has never been developed a closure for such a container l which is inexpensive to construct and which provides a tight seal for the contents of the con'- tainer.

It is the object of my invention to provide a tubular container with a closure having a clamping device which may be operated to press the closure member or head into firm engagement with the end of the container, so that practically an oil-tight seal is provided.

It is further my object to provide in combination with a drum and a head for the drum, for a clamping device which can be adjusted into clamping position by the simple manipulation of a bolt which extends from the clampingdevice to the head.

A further object is to provide a head having a nut mounted with such relation to the head, which nut receives the bolt extending from the clamping device, that there is no likelihood of the nut or threaded bolt contaminating the contents of the container, so that if edible products are Shipped in the drum there will be no likelihood of contamination from the clamping device, and there will further be no leakage due to the extension of the clamping adjustment device through the head of the drimi.

Another object is the provision of a clamping arrangement for a drum closure which will have members which will be forced into engagement with the drum closure in such a manner that substantial portions of the clamp will bear against the peripheral area of the head.

The above objects and other objects to which reference will be made in the ensuing disclosure, I accomplish by that certain combination and varrangement of parts of which I have illustrated a preferred embodiment.

Referring to the drawing:-

Figure 1 is a plan view of the drum closure.

. Figure 2 is a sectional view of a portion of the drum showing the closure in partially vclosed posltion.

Figure 3 is a sectional view of a portion of the drum prior to the tightening down of the clamping device.

Figure 4 is a sectional view of a portion of position.

- served that there are substantial areas 15 adthe drum closure when in completely clamped Referring to the gures, 1 indicates -the tubular walls of the container or drum. At the end the drum has a ledge-like annular anged B0 portion 2 and an inturned iianged rim 3 spaced slightly above the outwardly extending annular flange.

The diameter or internal peripheral dimensions of the anged rim 3 are less than'the 65 internal peripheral dimensions of the outwardly extending ange 2,y so that a head 4 having an annular flange 5 may be positioned so that its annular flanged portion 5 bears against the outwardly extending flange 2. An annular gasket 6 is ordinarily employed so that if the arrangement for clamping the head 4 onto the drum is satisfactory a tight seal will be made because of the gasket 6.

'I'he clamping device is composed of a hub 7 75 having an aperture 8 therein for receiving the shank of a clamping bolt, and spider arms 9 which extend out radially from the axis of the hub, but which incline diagonally from a line extending at right angles to the axis of the hub. vA bolt having a threaded shank 10 and a head 11 has its shank extended through the aperture- 8 in the hub, and when the clamp is attached the threaded shank engages a nut 12, preferably welded to the inner surface of the head, which nut is encased in a cover cap 13 which seals the nut and threaded shank from contaminating the contents of the drum.

Figures 3, 2 and 4. respectively, show the various positions taken when the clamping device is secured in position. 'Ihe head 4 is placed with its flanged portion 5 bearing against the gasket 6, and the clamp 9 is placed in position with the axis of its head aligned with the center of the aperture in the head through which the shank 10 of the adjustment bolt passes to engage the nut 12. In this position the ends of its spider arms will fit down through the internal peripheral edges of the inturned ange 3. As the bolt head 11 is turned, the ends 14 of the spider arms 100 seat in under the ange 3, and the spider arms begin to bear on the upper surface of the flange 5 of the head. In Figure 4 the clamping device is shown turned clear down, and it will be objacent the upturned ends 16 of the spider arms which bear rmly against the uppersurface of the flange 5, thereby causing a tight seal be-V tween the under surface of the flange 5 of the no head and the upper surface of the outwardly extending flange 2 of the drum.v 4

'I'he closure which forms the subject matter of my invention is inexpensive to construct and simple to adjust, and due to the prying down i'orce of the portions adjacent the ends of the spider arms, an exceptionally tight closure is provided.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-

1. A closure for a drum having aniinturned flanged rim comprising a head with a clamping device for securing said head in position on an end oi said drum, said clamping device comprising a hub having spider arms normally extending from said hub arcuately along a plurality of planes of the axis of said hub, and adjustable means connecting said hub and head for straightening out said spider arms thereby causing their ends to engage under said inturned flanged rim, said adjustable means comprising a threaded bolt with a nut secured on jsaid head which said bolt is adapted to engage, and a cover sealing said nut and threaded end of said boit from exposure to the contents of said drum.

2. In combination with a tubular container having an out-turned rim ledge and a rim flange spaced upv from said ledge and turned inwardly over the outer part of the ledge, and a closure member for the container of diameter to pass said ilange and rest its edge part on said ledge, a retainer for said closure comprising a series of resilient members having inner parts xed together and extending outwardly and downwardly from said inner parts so that said members are arched across said closure along a plurality of planes of the axis thereof, with their outer ends free and adapted to pass said ange and rest on said closure, and means to draw said inner iixedtogether parts down toward said closure, thereby distorting said members downwardly from their arched shape, whereby each member is extended under said rim ange and exerts leverage down on the closure with the rim iiange as the fulcrum.

3. In combination with a tubular container having an out-turned rim ledge and a rim flange spaced up from said ledge and turned inwardly over the outer part of theledge, and a closure member for the container ofdlameter to pass said flange and rest its edge part on said ledge, a retainer for said closure comprising a central hub and members fixed to and extending radially and downwardly from said hub in a plurality of axial planes so that said members are arched across said closure and their ends will pass said ange and lrest on said closure, the end part or each member being bent upwardly at a. distance from its end whereby its bend rests on the closure over the ledge, and means to draw said hub down toward the closure, thereby distorting said members from their arched shape to a flattened expanded shape, whereby each member exerts leverage with the bend of the member pressing on the closure over the ledge and with the raised end part of the member bearing up against the flange.
